Abstract (en)
[origin: EP1189435A2] It is intended to provide an image processing method, an image display unit, and a storage medium, capable of effecting an appropriate color reproduction even with a change in external environment. The image display unit according to the present invention which applies a desired image processing to inputted image data and then displays the image, includes: a 1<st> correction curve generating unit for generating a 1<st> correction curve for correcting a change in brightness of external illumination, a 2<nd> correction curve generating unit for generating a 2<nd> correction curve for correcting a change in color of projection plane, and a 3<rd> correction curve generating unit for generating a 3<rd> correction curve for correcting a change in color of external illumination. Therefore, it is possible to effect an appropriate color reproduction even with a change in external environment, since the desired image processing to inputted image data is performed on the basis of the generated 1<st> correction curve, the generated 2<nd> correction curve and the generated 3<rd> correction curve. <IMAGE>
